- Stainless Steel Sample loops for Rheodyne 7725 Series and 7125 Series valves are not interchangeable due to the change in port angle
- Actual volumes can differ due to tolerance of metal tubing bore - accuracy of large metal loops is ±5%, intermediate loops ±10%, small loops ±30%
- PEEK Sample Loops are inert to most organic solvents
- Wall thickness, temperature, exposure time and concentration of organic solvents affect the durability of PEEK tubing
- Concentrated nitric acid and sulfuric acid weaken PEEK tubing
- THF, methylene chloride and DMSO cause PEEK to swell
- Actual volumes can differ because of tolerance of tubing bore - accuracy of large PEEK loops is ±14%, intermediate loops ±21%, small loops ±65%
